Windows 10 looks like an improvement, as Microsoft struggled with Windows 8 so much so they are giving version 10 away for free to anyone with Windows 7 or 8 if you upgrade in the first year. This version will be compatible with all devices from a cell photo to an Xbox to your home computer. It has an improved UI and better power management for your devices. It also has a new photo app which may be handy for photographers. Check out all the details in this video by Computer Clan.
